"The original exposures of this granite were on Allotment 29, Section 4, Parish of Kunat Kunat, some 10km SSW of Lake Boga township in northwestern Victoria. The outcrops were only just exposed above the flat-lying Tertiary sands and nodular limestone. The first attempt at quarrying were between 1924 and 1927. Immediately after World War 2 quarrying recommenced and has been operating ever since.
Since the 1970's the quarry has been an important source of specimens for mineral collectors, especially for fine crystals of fluorapatite.
The Lake Boga granite is Devonian in age and belongs to the same suite as the nearest granites at Wycheproof and Pyramid Hill. The Lake Boga granite is extremely variable in texture in the uppermost 10 metres of its exposure, where the most common rock type is a pink to cream or grey equigranular leucocratic granite. Coarse patches and veins of pegmatite are widespread, with less common zones of banded aplite. Irregular masses of black schorl also occur. Miarolitic cavities up to 1 metre across and lined with fine crystals of smoky quartz, orthoclase,albite, muscovite and fluorapatite are associated with coarse pegmatite zones. Smaller cavities up to several centimetres across occur ia an equigranular phase of the granite, marked by coarse segregations of muscovite and biotite. Many of the phosphate minerals occur in the cavities in this rock type.
At deeper levels, the granite shows only occasional pegmatoidal zones and cavities." (Birch 1993)
